The Duolabs Diablo CAM 2, also known as D-Module 2, is a next-generation Conditional Access Module (CAM) designed by Duolabs for use with DVB-compatible set-top boxes via the CI (Common Interface) slot. It is a direct successor to the original D-Module, with substantial hardware upgrades across processor, memory, and security.

The module is aimed at developers and advanced users who require a fully customisable and programmable CAM — one that supports dual smartcard readers, bus encryption, and a flexible internal architecture based on FPGA technology.

Key Features

• ARM7TDMI processor running at 50 MHz
• FPGA processing at 100 MHz for dedicated signal handling
• Dual smartcard readers: one ISO-format and one Plug-In (SIM-format)
• Bus encryption for secure data transmission
• 2 unique serial numbers internally lasered inside the hardware
• PICO-OS operating system with FAT 12 internal filesystem
• Fully programmable via PCMCIA secure protocol
• New internal CPU core compared to the original D-Module

Product Benefits

• Doubled RAM (1 MB vs 512 KB on the D-Module) allows handling of more complex CAS operations
• Increased Dataflash (4 MB) provides additional storage for firmware and CAS data
• More powerful DVB processor (Xilinx 1200) improves throughput and reliability
• Bus encryption protects against signal interception and unauthorised access
• Dual smartcard slots give flexibility to accommodate different card formats in the same device
• J-tag connection supports low-level debugging and development workflows

Why You'll Love It

• Designed for maximum flexibility — the FPGA-based architecture lets developers customise the module's behaviour, unlike fixed ASIC-based CAMs
• Plug-In and ISO smartcard readers mean no adapters are needed for different card types
• Backward-compatible with DVB CI set-top boxes that accept the original D-Module
• Built-in security features (bus encryption + unique lasered serial numbers) provide tamper resistance
• Hardware-upgradeable design with J-tag support makes it suitable for development and testing environments
